(a) Lock-and-key model (b) Induced-fit model Substrates There are 2 models of enzyme function, the Lock-and-key model and the Induced-fit model. The induced fit model is the one more widely recognized as correct and more common in our bodies. What is the difference between them? The enzyme in the induced-fit model can only be used once, while the lock-andkey enzyme can be used over and over again In Lock-and-key, the active site (binding site) is the exact right shape to start, where the Induced-fit active site changes shape as the substrates bind The Lock-and-key model forms a tighter bond with the substrates in the reaction than in the Induced-fit model They result in different products being made
